Abstract

A closing member comprises a valve element formed of metal substrate on which a plurality of perforated openings are disposed along an endless circumference with equal intervals between them, and metal foil laminated to the inner surface of the metal substrate so as to close the perforated openings. When the internal pressure of a closed battery is elevated, portions of the narrow intervals of the metal substrate, which are deformable by a small force, are elongated so as to cause a portion of the metal substrate encircled by the plurality of perforated openings to be projected. The closing member having such structure is secured to the inner periphery of an open end portion of an outer container of the battery, which accommodates the electrode element consisting of a positive electrode, a negative electrode, and a separator, together with an electrolyte therein, so as to close the open end portion of the outer container.
